One brass jag covers the most popular bore diameter in shooting - .22 LR rimfire, .223 Remington, and 5.56 NATO all share the same 0.224" groove diameter. This .22 caliber brass jag grips a cleaning patch and forces it against the rifling with even pressure, wiping solvent and fouling out of the bore in a single pass. Brass won't scratch the barrel the way a steel or aluminum tip might.
Rimfire .22 LR leaves waxy lead residue that clings to the bore. Centerfire .223/5.56 produces copper jacket fouling and burnt powder carbon. Both types of fouling respond to the same technique: wet a patch with solvent, push it through on a jag, and let the solvent work. The gun cleaning jag makes this process faster and more thorough than a slotted tip because the patch wraps around the jag's pointed tip for full 360-degree bore contact.
After solvent passes, run dry patches on the jag until they come out clean. Finish with one lightly oiled patch for bore cleaning protection between sessions. This is the everyday workhorse jag - if you own any .22, you need one.
